Showing Difference between two datetime values in

Question

I am retrieving two date time values from the database. Once the value is retrieved, I need the difference between the two values. For that, I create a timespan variable to store the difference of the 2 date values.

TimeSpan? variable = datevalue1 - datevalue2;

Now i need to show the difference which is stored in the Timespan variable in terms of number of hours. I referred to TimeSpan.TotalHours but couldn't apply the same for some reason. How do I do that? I am using C# on a MVC project. I simple need to show the difference value in hours?

EDIT: Since timespan was nullable, i couldn't use the total hours property. Now I can use it by doing TimeSpanVal.Value.TotalHours;

Answer 1

Is there a reason you're using Nullable?

If you want to use Nullable then you can write variable.Value.TotalHours.

Or you can just write: (datevalue1 - datevalue2).TotalHours.
